A: $299.99
It was the first console that I bought on launch day. I had expectations, but they were all blown away by this new way to play. With so many fun games to play, both core and casual, it's been a blast so far. Here's to 2009. The extra $50 is because of all the new Sonic games coming out on the console. 
B: $99.99
I really do like this system, don't get me wrong. With games such as Left4Dead, Bioshock, and great marketplace games (Don't forget RE5 coming up soon), you can't go wrong with the console. However, my brother already has this... so it's like having a free console I can play any time I want. If I ever wanted to buy it for myself, it would have to be pretty cheap to get me over the freeloader hurdle. 
C: $99.99
With all of my time going towards Wii and 360, not to mention work and school, I haven't found a place for the PS3 yet. However, I would love to have a Blu-Ray player to watch The Dark Knight on (not to mention plenty of other movies), and LittleBigPlanet is a lot of fun. So if it ever came down to this price, I would definitely get it. Yeah, I doubt it will come down to this price... but that's what friends are for right? Not to say that it's a bad console (it's not), but right now I just don't have the time nor money to own this beast.
